Python – 通过分隔符连接元组元素

给定一个元组，通过分隔符连接元组的每个元素。

Input : test_tup = (“Gfg”, “is”, 4, “Best”), delim = “, ”
Output : Gfg, is, 4, Best
Explanation : Elements joined by “, “.

Input : test_tup = (“Gfg”, “is”, 4), delim = “, ”
Output : Gfg, is, 4
Explanation : Elements joined by “, “.

方法#1：使用列表推导

在此，我们使用列表理解中的循环迭代元组中的每个元素，并使用 +运算符连接。

Python3

# Python3 code to demonstrate working of 
# Concatenate Tuple elements by delimiter
# Using list comprehension
  
# initializing tuple
test_tup = ("Gfg", "is", 4, "Best")
  
# printing original tuple
print("The original tuple is : " + str(test_tup))
  
# initializing delim 
delim = "-"
  
# using str() to convert elements to string 
# join to convert to string
res = ''.join([str(ele) + delim for ele in test_tup])
  
# striping stray char 
res = res[ : len(res) - len(delim)]
  
# printing result 
print("Concatenated Tuple : " + str(res))

输出

The original tuple is : ('Gfg', 'is', 4, 'Best')
Concatenated Tuple : Gfg-is-4-Best

方法 #2：使用 join() + map()

在此，我们使用 str() 将所有字符转换为字符串并映射以对所有元素执行 str()，然后使用 join() 连接。

Python3

# Python3 code to demonstrate working of 
# Concatenate Tuple elements by delimiter
# Using join() + map()
  
# initializing tuple
test_tup = ("Gfg", "is", 4, "Best")
  
# printing original tuple
print("The original tuple is : " + str(test_tup))
  
# initializing delim 
delim = "-"
  
# for joining, delim is used 
res = delim.join(map(str, test_tup))
  
# printing result 
print("Concatenated Tuple : " + str(res)) 

输出

The original tuple is : ('Gfg', 'is', 4, 'Best')
Concatenated Tuple : Gfg-is-4-Best
